Power monitoring system SL-Sys™ liquid

for optical lens production

The complete solution for liquid lens testing to ensure quality and optimize production lines. Measure optical power and hysteresis of the power curve independently depending on applied voltage Assess the optical quality, prism and centering errors individually compared to optical power Determine temporal transient response dynamic including optical power and aberration evolution while applying voltage Gage applied voltage at the lens' outer edge, overall consumed current and the ratio of applied versus consumed voltage Welcome to the future of liquid lens testing. The SL-Sys is a turnkey solution that provides industrial liquid lens manufacturers with an unparalleled quality control platform. It enables you to go beyond current testing methods that rely solely on focal length and MTF measurements by ensuring the overall lens quality as a function of true optical quality, directly on the production line. Inside the system’s sleek outer casing is a technology treasure chest that includes a fully-calibrated, solid-state1 optical bench that ensures perfect optical conjugation between the lens and the testing plane. Quality control is fast, simple and reliable via an ergonomic PC software interface. Each unit contains perfectly collimated light source functioning at 630nm, an AC generator that provides ±10V of power with 16 bit resolution, a 20x charge amplifier, and a system that synchronizes the wavefront sensor with the generator. As an added security feature, electric current to the lens is cut as soon as the access panel is opened.
